Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Wherein: 1, Round butt, 2, lock dog pole, 3, maintenance connecting rod, 4, fastening jam plate, 5, reset tension spring, 6, lock ring, 7, lock dog.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is made to brief description.
As shown in Figure 1, mould and cover tightener, comprise Round butt 1, lock dog pole 2, maintenance connecting rod 3, fastening jam plate 4, reset tension spring 5, lock dog 7 and lock ring 6; Described in it is characterized in that, mould and cover tightener outside and be provided with Round butt 1, in described Round butt 1, be provided with lock ring 6, described lock ring 6 is provided with fastening jam plate 4, described fastening jam plate 4 is provided with lock dog 7, described lock dog 7 is provided with lock dog pole 2, described lock dog pole 2 is provided with maintenance connecting rod 3, between described Round butt 1 and lock dog 7, is provided with reset tension spring 5.
Operating sequence: the first step, will mould a barrel tightener and lie in and mould on bung, the tightener Round butt 1 of holding with a firm grip.
Second step, draws holding position connecting rod 3 with thumb.
The 3rd step, pull-up lock dog pole 2.
The 4th step, lifts fastening jam plate 4 naturally.
The 5th step, bung is inserted in internal diameter expansion, then unclamps maintenance connecting rod 3, compresses fastening jam plate 4, under reset tension spring 5 effects, clamps bung outer rim, starts operation.
Task program: the both hands Round butt 1 of holding with a firm grip, rotation lock dog pole 2, the angle of lock dog pole 2 changes fastening jam plate 4 thereupon and moves down, and causes internal diameter to dwindle and compression barrel lid outer rim.More press and tightlier produce very large friction force, tighten bung simultaneously, unload while cover tightener use conversely, operating sequence is identical, and firmly contrary, action direction, tightly covers up time and operate along pin, and during pine lid, conter clockwise operates.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
